Handmade envelopes. I plan to delete this listing tomorrow. Thank you for your interest. I am also selling on other sites, so please feel free to comment. There are 20 sheets. I have other items for sale as well, so I would be happy if you would take a look. Standard size. How about original envelopes? They are all handmade. I would be happy if you would consider them. Please purchase only if you understand handmade items!
